Looks pretty accurate. A Talon with a MBC and the cheap mods usually traps at about 100 mph so that'd compare to the Neon's traps and the race we saw.
I assume the WRX in the video didn't have a boost controller. Again, that's all it would take to even things up quite a bit.
Turbo upgrades won't be all that expensive. DSM owners have been buying exhaust manifolds along with their new turbos for years because the 95-99 manifolds are much better. With 2.4 liters their choice of turbos is much nicer too - they can get a larger turbo than most 4 cyls choose because they can spin 'em up faster. Too bad there will be such a traction issue at that point.
